The list price for the Bose Basic Package is $1699.99 which includes the L1 Cylindrical Radiator Loudspeaker the PS1 Power stand, the R1 Remote control and the carry bags.

The Single Bass Package is listed at $1999.98 and it includes the basic package components plus B1 Bass Module.

The Double Bass Package lists at $2297.97. It includes two B1 Bass Modules.

To my knowledge GC and Bose are the only ones selling this system.

As has been suggested the only way to reduce the cost is to have something to trade.

I don't know how Bose gets away with what appears to me to be price fixings but ---

Have a Great Day!
